Nearly 190,000 have been killed since the Syrian civil war
Syrian capital killed 11 children on Wednesday, a monitoring group said, with activists saying a school had been hit.
"Eleven children were killed in shelling of the part of Qabun district that is out of government control," the Syrian Observatory for Human Rights said.
Activists accused President Bashar al-Assad's forces of the killings, which they described as a "massacre of children".
The Syrian Revolution General Commission, a network of activists across the war-torn country, said the shelling hit a school, and an activist group in the neighbourhood shared a grisly video of the aftermath.
The footage posted on the group's Facebook page showed the bodies of at least nine children lying on a white tiled floor, some of them surrounded by smears of blood.
